Decay Rate
Specify the rate at which the light intensity decreases in function of the distance to the light source. The available values are:
No Decay | Light intensity remains constant with respect to distance. |
|---|---|
Linear | Light intensity decreases linearly with distance. |
Quadratic | Light intensity decreases proportionally to the square of the distance. This is the physically correct behaviour. |
Cubic | Light intensity decreases proportionally to the cube of the distance. |
